Nah I did not get 5/10 for multiple choice wth

For question 29) b) would I lose a mark if I didn't make the piecewise function????

wondering the same, im pre sure we would lose a mark tho since 1 mark for integration and 1 mark for domain restriction

Found this but it's not a clean version and some answers may be wrong. At least you can see the questions. Clean version will be on nesa website soon anyway.

2xq and 187 are the goats

what r we predicting for the raw b6 cutoffs? was it harder than 2022?

Slightly harder

How did the exam go?

decent

 

[Bigbanger666]

damn aight probably lost a mark there
might have screwed up integration and got -2 somewhere lol

You had to integrate and find the value of +C which was 2 giving that value

yall for the koalas question did u have to round down or up? I thought since it asked for expected koalas and the answer came to 36.72 u rounded up?

no you round down because the question asked how many koalas weigh more than 11.93kg. so there were 36 whole koalas above 11.93 and then you don't consider the .72 because that's not a whole koala if you get what i'm saying. normally, yes you would round up, but in this case you wouldn't because of the question. hope that helps.

Solutions:

im p sure 360 is also a solution for the trig Q along with 0 and 300, also feel like i got a 90-95 raw depending on how generous they r with working marks slayy

 

[dumplingky]

im p sure 360 is also a solution for the trig Q along with 0 and 300

yeah because the boundaries were inclusive of 300

Can someone explain why this sheet say question 9 is not c isnt (even)^2 and (odd)^2 even regardless

i did the rough mark and i probably got about a 60% on that exam, my biggest mistakes was trying to find the area bounded by the two curves and y axis and i only just realised i didnt have to make x the subject but could of just put the boundaries of the x value instead of find the y intercept and integrating the curves for x equals. so probably got 1/3 for that as i bs the stuff out of that question :C,
so what are my chances of a band 4??

And for the question 30

Did anyone just guess when Cos(x)=sin(x) in there calculator i found 45 degrees converted it to radians got pi/4 then added 4pi/4 to it

grr I put C as well woulda been ez 95 raw if I never put C
say u have an equation like this as f(x):
[(x)^3 - (x)^2]^2
and then obv f(-x) would be
[(-x)^3 - (-x)^2]^2
no matter what number u sub in they'll be different
rip 🪦

but it just says which one will always be positive

Edit: just realized how math worsk 3x3=9 oddxodd=odd evenxeven=even evenxodd=even i was thinking of (-x-=+) (and +x+=+) there goes another mark

OM

OMD that's exactly what I did W technique honestly, I think they will give you the mark for it cause u did it correctly.

 

[eskiiiiiiii]

Oh rip there goes a mark

You could leave it to 2 dp cuz there was a question that was exactly the same in 2021 hsc where there was like 54.4 babies (i don’t remember the right number)

no this is legit why I left it not rounded because in that practice papers they left it unrounded also

No I have fx8200 AU

Was the 2022 math adv paper harder than this years?
